Abstract
A method is for medical imaging of a patient using a medical imaging system with ECG triggering. In an embodiment, the method includes capturing a respiration signal of the patient including n respiration cycles; concurrently capturing an ECG signal of the patient including m heartbeat intervals; determining a respiration-dependent heartbeat model based upon the n respiration cycles and the m heartbeat intervals; specifying at least one trigger time-point based upon the respiration-dependent heartbeat model; and starting the medical imaging at the specified trigger time-point.
Claims22
A method for the medical imaging of a patient using a medical imaging system with ECG triggering, the method comprising:
- capturing a respiration signal of the patient, the respiration signal including n respiration cycles;
- concurrently capturing an ECG signal of the patient, the ECG signal including m heartbeat intervals;
- determining a respiration-dependent heartbeat model based upon the n respiration cycles and the m heartbeat intervals;
- specifying at least one trigger time-point based upon the respiration-dependent heartbeat model;
- and
- starting the medical imaging at the trigger time-point specified.
A computing unit for medical imaging of a patient using a medical imaging system with ECG triggering, the computing unit being designed to
- capture a respiration signal of the patient, the respiration signal including n respiration cycles;
- concurrently capture an ECG signal of the patient, the ECG signal including m heartbeat intervals;
- determine a respiration-dependent heartbeat model based upon the n respiration cycles and the m heartbeat intervals;
- specify at least one trigger time-point based upon the respiration-dependent heartbeat model;
- and
- start the medical imaging at the at least one trigger time-point specified.
A system for medical imaging of a patient via a medical imaging system with ECG triggering, comprising:
- a capture unit designed to
- capture a respiration signal of the patient, the respiration signal including n respiration cycles, and
- concurrently capture an ECG signal of the patient, the ECG signal including m heartbeat intervals;
- a computing unit designed to specify
- a respiration-dependent heartbeat model based upon the n respiration cycles and the m heartbeat intervals, and
- a trigger at least one trigger time-point based upon the respiration-dependent heartbeat model;
- and
- a medical imaging system designed to start the medical imaging at the at least one trigger time-point specified.
